OS/Distribution

Recalbox

Raspberry Pi 3 Model B

SOMMAIRE

• 1-Infrarouge-télécommande: recevoir et décoder les signaux infrarouge de la télécommande Nuxii. Naviguer dans les menus, de contrôler retroarch (LOAD/SAVE,QUIT,RESET....), ou votre environnement linux simplement depuis votre télécommande
• 2- LEDS: allume une led verte lorsqu'un jeux est lancé et une led rouge quand vous êtes dans le menu
• 3-Bouton:Eteindre le Raspberry Pi
• 4-LCD:Afficher la consommation CPU/Memoire, la température, l'heure...
• 5-LED RGB: Tuning Led RGB

Utilisation
